SUZAXISLOG - Suzaku XIS Configuration Log

The Suzaku XIS detector units can be configured differently depending on how
the user chooses the observation to be carried out. This database table
records for each Suzaku observation the different XIS configurations during an
observation for all XIS units. The set of parameters that can be configured
are: datamode (see also edit mode), window size, on-board window
discriminator, on-board grading and event threshold. Each record lists for a
given XIS the values set for these parameters in the time interval where they
are valid within the observation. Therefore for a given XIS there will be as
many records as many different configurations are present within an
observation.

Psum_Line
The number of lines that are summed when the Psum clock is in use.

Area_Hstart
This gives the start address of the horizontal area discriminator set on board.
It consists of a string with four numbers, each corresponding to each individual
segment of the CCD (A, B, C, D).

Area_Hstop
This gives the stop address of the horizontal area discriminator set on board.
It consists of a string with four numbers each corresponding to each individual
segment of the CCD (A, B, C, D).

Area_Vstart
This gives the start address of the vertical area discriminator set on board.
It consists of a string with four numbers each corresponding to each individual
segment of the CCD (A, B, C, D).

Area_Vstop
This gives the stop address of the vertical area discriminator set on board.
It consists of a string with four numbers each corresponding to each individual
segment of the CCD (A, B, C, D).

Discr_Type
This indicates the area discriminator type if it is applied outside (set to 0)
or inside (set to 1). It consists of a string of four numbers, each
corresponding to each individual segment of the CCD (A, B, C, D).

Grade_Telm
There are four types of grade on board: OTHERS, TRAIL, LEAD, SINGLE. This
parameters reports a string with four numbers, each indicating if any of
these types of grades are sent to the telemetry. The possible values of each
number are 0 (indicating the grade type is not sent) or 1 (indicating the
grade type is sent). The grade discriminator is used only in the timing mode.

Evtthre_Low
This give the lower-level discriminator applied on-board to events. It consists
of a string with four numbers each corresponding to each individual segment of
the CCD (A, B, C, D).

Evtthre_Up
This gives the upper-level discriminator applied on-board to events. It
consists of a string with four numbers each corresponding to each individual
segment of the CCD (A, B, C, D).

Area_Discr
This parameter indicates the area discriminator status for each segment of
the CCD. It consists of a string with four numbers each corresponding to each
individual segment of the CCD (A, B, C, D). The possible values are 0 for
disabled and 1 for enabled.

Grade_Discr
This parameter indicates the grade discriminator status for each segment of
the CCD. It consists of a string with four numbers each corresponding to each
individual segment of the CCD (A, B, C, D). The values are 0 for disable, 1
enable. The grade discriminator is used only in the timing mode.

Conf_Type
This parameter identifies the specific configuration of the area and grade
discriminators and the event threshold. The same string is used in the
filename. The value for the standard configuration is 'a'.

Filename
The name of the XIS file that contains the data with the configuration settings
described in this record.

Processing_Date
This records the date when the data were processed.
If a data set has been processed more than one time, it reports the date
of the last processing.

Processing_Version
This records the version of the processing script used in the pipeline to
generate the data products for the observation.

Num_Processed
This records the number of times a data set has been processed using the same
processing version of the script.

Injection
This is a flag which identifies whether or not the observation was carried
out with charge injection in the XIS.
